Abstract Using orthogonal design,optimization design of rotational flow self-priming pump body structural parameter was done through simulation.Orthogonal scheme of four factors and three levels was designed,the influence of geometrical parameters on the characteristics was studied,and optimal scheme of the characteristics was found by analyzing the contrast of performance curves.The influence orders of geometrical parameters to the four characteristics were obtained by using range analysis.The optimization parameter combination was obtained by comprehensive balance analysis and comparison to the data result.For the optimization parameter combination is not in the original design schemes,the redesign was made based on the analyzed result.The performances between the additional scheme and original schemes were contrasted,and the optimal scheme was determined.The results are instructive to the optimization design of rotational flow self-priming pump.
